Usually their bottoms are on the ground. They often occur during dust storms, sandstorms, tornados. THe dirt particles suspended will separate out once the air stands still for a time. Their transparency is dependent on whether one is experiencing such a cloud (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVin9JwpEbGdrcN5Y29ycA" class="cyc_term">AmbientConditionsMt</a>), or describing one in the abstract (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViHyZwpEbGdrcN5Y29ycA" class="cyc_term">WeatherProcessMt</a>). cloud of water CloudOfH2O A cloud of particles of liquid or solid water in the atmosphere covering a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViACZwpEbGdrcN5Y29ycA" class="cyc_term">GeographicalRegion</a>.

Pretty String (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> TERM STRING) means that STRING is the English word or expression (sequence of words) commonly used to refer to TERM. The predicate <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> is used by the code which generates CycL to English paraphrases, but its applicability is not restricted to this use. prettyString cloud CloudlikeObject A cloud is a kind of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi_ypwpEbGdrcN5Y29ycA" class="cyc_term">Suspension</a> that has air as the suspending fluid.

Aerosols are suspensions of small particles in a gas. Aerosols can be dispensed from aerosol cans, but can also occur naturally. ExistingStuffType type of temporally and spatially stuff-like thing A collection of collections, and a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a>. Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVny6pwpEbGdrcN5Y29ycA" class="cyc_term">ExistingStuffType</a> is a collection of things (including portions of things) which are both temporally and spatially stufflike. Division in time or space does not destroy the stufflike quality of the object (down to a certain granularity). <p/> <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> <b>STUFFTYPE</b> <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVny6pwpEbGdrcN5Y29ycA" class="cyc_term">ExistingStuffType</a>)</code> implies both (i) for most instances <code><b>STUFF</b></code> of <code><b>STUFFTYPE</b></code>, for any proper physical part (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r8a2smPXcQdiEoJhcx65EiQ" class="cyc_term">properPhysicalDecompositions</a>) <code><b>PART</b></code> of <code><b>STUFF</b></code>, <code><b>PART</b></code> is also an instance of <code><b>STUFFTYPE</b></code> and (ii) for all instances <code><b>STUFF</b></code> of <code><b>STUFFTYPE</b></code>, for most proper physical parts <code><b>PART</b></code> of <code><b>STUFF</b></code>, <code><b>PART</b></code> is also an instance of <code><b>STUFFTYPE</b></code>. <p/> For example, every piece of wood is temporally stufflike: if W-168 is a piece of wood during 1996, then it's also a piece of wood for the one-minute time-slice 9:05am 7/7/96. It's also spatially stufflike: if we take that piece of wood W-168 and cut it in half, we have two things which are both pieces of wood.
